Long time no post! Thought you guys might enjoy a low quality video from LS in May: https://www.youtube.com/watch?v=tdPkXqiC938

Damn ill have to look into that.. Wonder if the harness setup I have would plug and play... Thanks for the info/compliment!

It's a great bit of kit, and if you do the math it virtually pays for itself in dyno tuning cost savings. It's easy to change any setting, watch what's going on, log data, etc. Super convenient!

I think you have to get the Holley harness. It's a proprietary plug setup on the ECU. That said they have a basic harness that gets you from the ECU to pig tails with defined pin-outs.

It's mostly a time issue for me. Hard to balance work, life, family, race car habit...

I hear that. Juggling priorities..

That car belongs to lsm3 he lives in Sacramento. Believe he just finished it not too long ago. Nate who tuned yours? I need to get dyno tuned..

Beautiful car there!

I went the Holley EFI route for tuning. I highly recommend it. I got tired of paying tuners to chase peak power only to be left with a mess in the midrange. The Holley system uses your defined AFR and timing maps as inputs and then "self tunes". Basically it's changing your fuel map on the fly as you drive, under load. You can pick how aggressively it makes the changes, and the ranges of load, rpm, temps, etc that you want it to focus on. It took less than an hour to get it driving, then it just hones in on your AFR.

It also has built in traction control functionality, E85 controls, etc. Load a safe tune for the track, a fun tune for hooning about back roads, and an economy tune for road trips all at the touch of a button (well, LCD icon). I'll only be going to the dyno for bragging rights now...

Here is a good little write up on the system: http://www.johnnycichowski.com/2011/...ey-hp-efi.html

That makes sens as Catunes is in Sacramento. Didn't know lsm3 lived out there though. Hope I get to see his car some times soon.

Cheers! The cost is mostly time with this car. I think a similar build with fewer bells and whistles could be achieved ~10k. Just a lot of time...

Maybe I'm the 2nd! The wiring was all Holley and my messes.

This is the other one I know of. Dont have many details though as it was at my friends shop while I was out of town, so I never had a chance to go check it out.

Can you give me some insight on what you did with the p/s pump to the hydroboost? I'd like to lose my fluid reservoir if possible

You Bet. The PS lines go like this:

Pump > Hydroboost > Rack > Tank w/filter > Pump

I used this tank/filter: http://www.pscmotorsports.com/motors...-hose-kit.html

-And with the tank above you can run the return off the Hydroboost back to the tank as well. It has two inlets and one outlet.

awesome car Nate -- looks like you did a great job on the swap. I'm close to making mine run, I can't wait to take it for a ride, must be a great feeling.

Cheers! Hang in there, it's last bits that take forever. The final product is good fun though, and well worth it!
